+1 please!! Probably a simple voltage divider network, but I've heard about the use of inductors to retain high end so unsure of the internals. Or if there are any other designs that achieve the same thing I would be interested in ideas

If you mean you lose treble when you turn down the level pot, then you could probably add a so-called 'treble bleed' cap and resistor in parallel across pins 2 and 3 of the pot, like what is done for guitar wiring. Typical values are say R=150K and C=1nF.

Try it out with some test leads with alligator clips first, see if it makes an acceptable difference.

Yes, it will lose treble when turn down the level pot. I will try per your information. Thank you
